BOARD PRY Eldon L. Krieg, South Whitley, Ind.

Application October 3, 1945, Serial No. 619,955

7 Claims. (01. 254131) My invention relates broadly to tools and more particularly to a construction of tool for removing boards or siding from studding or rafters with minimum injury to the boards for preserving the boards for reuse.

One of the objects of my invention is to provide a simplified construction of tool which may be used as a pry in removing boards or siding from studding or rafters without splitting or injuring the boards and thus preserving the boards for reuse."

Another object of myinvention is to provide a construction of tool having lug projecting members connected to a bodystructure and which may be manipulated in positions between studding and boards of siding thereon for quickly and easily removing the boards or siding from the studding. l

Still another object of my invention is to provide a construction of tool consisting of a tubular body structure and integrally connected lugs extending-in planes substantially normal to each other and having means for engaging studding in oneplane andtheboards or siding which is attached thereto in'another plane for exerting through leverageipressure forces for removing the boards or siding from the studding while preserving the boards or siding against damage for enabling reuse of suchboards or sliding.

Other and furtherobjects of my invention are the production of a simple tool serving as a board pry as set' forth more fully in the specification hereinafter following by reference to the accompanying drawings in which: i

Figure 1 is a perspective view of a board my tool emb'odyingmy invention andshowing the tool in'position for removing a board fro m a studding or rafter; Fig. 2 is a side elevational view of the tool of my invention; Fig. 3 is a horizontal sectional view taken on line 3-3 of Fig. 2; Fig; 4

is an end view of the board pry looking in the and used. asa pry for removing boards or-siding from studding or rafters without splitting or injuring the boards more quickly and easily than by the use of ordinary hammers or pry bars for preserving the boards for reuse. I provide a tool formed from a tubular bodystructure having lugs 2 integrally connected therewith andextending in planes substantially at right angles to each other, the shape of the tool being such that one set of lugs may be engaged with respect to the studding while an applicator pivotally mounted on the normally arranged lug or lugs may be applied against the surface of the board'associated with the studding and which is to be'removed Without injury. The applicator for engaging the board to be removed may be constructed in various forms such as for example a pair of pivotally mounted applicator members symmetrically journaled on opposite sides of a lug projecting from the tubular body structure of the tool or a single applicator member journaled between a pair of lugs projecting from the body structure of the tool and associated in either arrangement with lugs extending substantially normal to the plane of the aforementioned lugs and integrally related to the body structure of the tool and serving as a fulcrum member with respect to the studding from which the boards are to beremoved. By reason of the symmetrical construction of the board pry of my invention it is possible to use the board pry either to the right or the left of studding and/or to apply leverage to the board structure of the tool either inside or outside of the building of which the studding and attached boards forms part of the building structure. I have used the tool of my invention as described herein with very satisfactory results and while I have shown the tool in certain preferred forms I realize that changes in design may be made and I intend the structure shown herein to be regarded in the illustrative sense and not inythe limiting sense as I desire to include allsuch modified forms within the scope of my invention.

Referring to the drawings in detail reference character I designates a tubular body structure forming part of the tool of my invention. The tubular body structure I has a pair of transverse- 1y extending lugs 2 and 3 weldedor otherwise integrally connected with the tubular body structure 1 adjacent the end of the body structure. Adjacent the opposite end of the tubular structure l I provide an arm for extending in a plane substantially normal to the plane of the transversely extending lugs 2 and 3 and welded orintegrally connected with the tubular body structure l. The arm 4 is curved in a direction toward the end of the tubular body structure lwhich includes the integrally connected lugs 2 and 3 and terminates in a position spaced from the tubular body structure I. The end of the arm it; serves as a journaling means for theapplicatcr members or pressure feet and B which are journaled arm 4. The pressure feet 5 and 6 are symmetrie cally formed and are balanced to pivot about the center formed by pivot pin I and are each formed with a straight edge 5a and 6a and rear curved edges 5b and 6b. The length of the pressure feet 5 and 6 is such that they clearthe distance be'-:-

tween the center of pivot pin 1 and the surface of the tubular body structure I thereby permit--- ting the pressure feet to be angularly adjusted to' 'that position in-wh'ich the board pry may progressively function most'easily in the process of applying pressure against the under surface oi board 8 forremovingthe board from nailed positi-oh witl'f resp'ect'to studding or joist 9.'

NhandIe bar I El -is inserted into the interior of tubular-"bodystructure I when the board pry is to b'e olderatedfromthe inside of the building structure; If the board'pry is to be operated from tl'ie outsideof'the building structure, the handle 'bar is removed-from the position It] andutilized inthe po'sition II' on the outside of the building structure? The handle may be slid through the interiorof the'tubular body structure I to protrudeon either end thereof depending on which side OFtheboardS andstudding the'tool is used.

The h'andle bar is secured or locked in a desired selcted'position for obtaining the required leverageby means of the thumbscrew represented at l2? The'liigsi and 3"which are engaged against the rafters or' studding project on opposite sides of the tubularbodystruoture l and are provided with straightedge'engagingfaces 2a and 3a and curved rear"edges 2b and 3b, permitting the tool t'ti' b'e' inserted-"in a minimum of 'space'ior obtaining'*th'e--required fulcrum on either the left or right h'andsid ofthe rafter; studdi'ng or joist 9.

Ifi'a'modi'fied form of my invention I may'providtl'ie pry with a pa r of projecting arms M and |5 insteadofasingle arm 4 for embracing oppositesidsof'a' single pressure foot l'a instead of a 'p'air'of ressure feet 5 and 6 as heretofore ex lained The single pressure foot 16 is journale'd at 'l'Finthe two' arms [4 and [5. This arrangement 'may be simpler to o erate under certain"-condi'tions as the width of the pressure applicator'isIeSsinthe arrangement shown in Fig. -6'-"than"thearrangement illustrated in Fig. 5 and thereerefin tances in which it is necessary to worhu'nder extremely confining positions where spacel mitations are very severe.

Intheuee-ofthe tool of my invention an initial or'-'topb'oard"is generally removed by hand or'by the usual m'eans to expose the studding. Then, tomemove"thesuccessive boards from a position inside the studding or the building; lug 2 can be lioolfed onthe outer sideof the studding Qand tlie"pressure-'fe"et 5 and '6 may be placed "against tlieinsi-deoftheboard- B'which is nailed to joist Qandthena" downward pressure exerted on the Handle bar l0-'to'-develop the required leverage for-forcing -the board 8 outwardly away from the studdi'ngfl" To remove-the board's 8 from the studding from a position outside of the building structure the handle bar is inserted in the tubular structure I in the position [I with the end of the handle bar protruding outside of the building. An upward pressure is then exerted on the bar I l to pry the boards 8 off of the studding 9.

The action of the tool is such that the boards may be pried oiT of the studding or rafters without splitting or damaging the boards; this may be accomplishedemore easily; and lgrapidly than by theusu'almeans; thus saving both material and labor; and the tool of my invention is capable of manufacture and production on a mass scale atlow cost.

While I described the tool of my invention in certainof itspreferred embodiments I desire that itbe unders'tood-that no limitations upon my invention are intended and that modifications may be' made within the scope of the appended claims without departing from the principles of my inventionza,
